make-like

An opinionated application template builder for LIKE applications

make-like is an application template builder for LIKE (Lisp In Kubernetes + Emacs) applications.

It will create the basic foundation for LIKE applications, including:

Makefile support for
- Running the application locally
- Running the application as a container, managed by podman, allowing you to add additional services (postgres, etc) to the pod.
Github Actions support for CI testing
Smart caching of quicklisp contents in the case of container builds

The application code itself is minimal, but provides some useful foundation elements:

Prometheus metrics support
Support for TOML-style config.ini files for application configuration
Git tag-based application version strings
Sly/Slime support when run in podman-managed containers
easy-route preconfigured with health-check and static image/js/css content routes

Tutorial

Create a likefile with contents similar to this:

(make-like:make-application
  :app-name "simple"
  :author "Anthony Green <green@moxielogic.com"
  :description "A simple sample application"

Run the make-like command:

$ make-like likefile
$ cd simple/
$ find .
.
./static
./static/js
./static/images
./static/css
./dist
./src
./src/package.lisp
./src/simple.lisp
./src/simple.asd

./build
./build/Dockerfile.base
./build/Dockerfile
./test
./test/config.ini
./test/test.sh
./test/podman-start.sh
./test/test-pod.yml
./Makefile

The make targets look like this:

$ make
Supported targets:
 clean          - clean the source tree
 podman-start   - run in podman using test/test-pod.yml
 podman-stop    - stop the test pod
 run            - run locally

To run the application in a container, do this:

$ make podman-start
[ LOTS OF OUTPUT REDACTED ]
Waiting for http://localhost:8080/health
===========================================================================

Application: http://localhost:8080

Prometheus : http://localhost:9101/metrics

Use emacs to 'sly-connect' to localhost port 4005

Run 'make podman-stop' to stop the test pod
